Letters Patent No. 109,440, dated November 22, 1870.

`IMPROVEMENT IN ROADSCRAPERS The Schedule referred to in these Letters Patent and making part of the same.

To all whom t may concern:

12e it known that I, XVILLIAM il?. Nlcnons, of Chicago, in the county of Cook and State of Illinois, have invented anew and improved Road-Scraper; and I do hereby declare that the followingis a full, clear, and exact description thereof', reference being had to the accompanying drawing making part of this specification, in which- Figure 1 is a top view of the improved scraper.

Figure -2 is a view of one side ofthe scraper.

Similar letters of reference indicate corresponding parts in the several gnres..

This invent-ion relates to an improvement on scrapers for clearing and leveling roads, which are adapt-ed for being drawn by animals, and guided and controlled by persons walking behind them.

lheohject of my invention is to hinge or pivota scraper, hereinafter described, to bails, which are applied to a draft-pole, and which are spread apa-rt and stiiiened by-means of a cross-bar securedto the rear end of the draft-pole, as will be hereinafter explained.

rIhe followingdescription will enable `others skilled in the art to understand my invention 1.,

In the accompanying drawingy A represent-s theV bedcf the scraper, which isa board of suitable widthaiid length, shed on its scraping edge with a metal plate, a.

The front and rear edges of the scraping bed are parallel to each other, andthe ends are sloped oft backward. Y

rlhis bed is strengthened by means ot' ribs'b b I) b secured to its bottom side, and tapered at their iront ends to correspond with the bevel of the scraping edge of the bed.

The rear ends of the rihsbbb b are extended outin rear of the back edge ci the bed A, and have secured transversely across them a bar, B, which serves as the handle by which a person can control the scraper while it is being drawn along.

'lo the back side ot' the scraper-bed A, near its ends and a little in rear ot' its scraping edge, staples g are inserted, which receive the hooked ends c of pole-rods I) l).

These pole-rods constitute adraft-bail, and are secured to the draft-pole C as follows:

'.lhe iront ends of the rods I) D are secured fast to the sides of the pole C the rods are then extended backward and outward through notches made into the extremities of a cross-bar, C', which issecnrcd to the rear end of the pole, as shown in the drawing.

From the ends of cross-bar C' to the hooks c c the rods D I) spread outwardly and are bowed, as shown in fig. 2.

rIhe cross-bar C serves as a brace for the draft-bail, and the front portions of the bail-rods serve as a brace for the cross-bar.

The advantages of the scraper are- IPirst,-that it is lighter, cheaper, and easier handled than any other.

Second, that, being att-ached to a draft-pole, it is much nrore easily worked with the team than being doubling up or getting over the traces.

Third, the draft from the ends and rear give it more power to eut in hard soil for this reason. When it is depressed almost to a level the draft is practically transferred to the very edge, and one man can hold it in that position in the hardest ground against the power ot' ten horses.

.I ain now nsing these scrapcrs in my own work, and

ind that they do double the work of anyscraper I have yet used. Y

vI am aware of the Scrapers patented to Thos. Penrose, Julie 27, 1854, and H. A. Maybee, May 26, 1868, and therefore do not claim anything shown in these patents; but, as in neither of these patents nor in any scraper having a bail pivoted as I show have a brace and tongue been combined with the bail,

I do claim as my invention and desire to secure by Letters Iatent-- 1. rIhe arrangementot' the bail D, fastening c g, brace C', tongue C, and scraper a A B, substantially in the manner described.

2. rIhe combination ot' the tongue C, brace C', bail D, and scraper A a B, snhstantiallyin the manner described.

3. The bail l), braced at C', and attached to the tongue C, and made exible between its brace C and its hooked ends c c, iu combination with the roadscraper, in the manner shown and described.
